[FOR SALE] Complete Custom 3.5'' Exhaust

[Megan370z]

Updated info about the complete N/A Package Deal on post # 12

I'm wondering if anybody could be seriously interested into my custom exhaust.


the kit include the whole exhaust setup which is;

- Modified Momentum headers (not the z1 copy)
- Custom Y-Pipe 2.5'' paired with a transition & megaphone to 3.5'' single exit.
- Custom 3.5'' mid pipe with a 18'' resonator.
- Custom Muffler section 3.5'' in & out.
- 2x HFC (y-pipe)
- 2x Resonator (y-pipe)
- Custom rear holding bracket (with bolts)
- All mandrel bent 304SS tubing.
- TIG Welded and Back-Purged for improved stronger welds.
- Equipped with modified V-bands to reduce turbulence.
- No gasket required.
- Much improved scavenging effect due to the both transition and megaphone *Header & Y-Pipe* which mean more power !
- With the benefit of V-Band the swap of those parts can be done in 10 mins ! (either 2x resonator or 2x HFC)





You will need to remove the rear bracing tower shown in the bottom Red square
Edit ; The G37, 350z, G35 has the same setup. Only the 370z has the V-Brace which isn't absolutely needed . The G37 share the exact same setup as the 370z but does not include the V-brace and that big Tower for the brace on the 370z.


then install the provided *blue* rear holding bracket
the 2 holding bolts goes into the already installed welded nut into the frame.
and you will lose the 2 braces going to the front bolts of the sub-frame.
IMO they arent crucial to the rear stability since the 350z does not have it and have the same sub-frame setup.


Ofcourse you will need to remove the rear fog light and slightly cut a circle in it ....



you will have an improved ground clearance since everything was installed to be as close as possible to the frame.

as a bonus half of the exhaust were heat wraped with DEI titanium (100feets of it)


serious buyer only please.

Sorry I do not have a VQ37VHR (VVEL) dyno. since I have the HR heads.
IMO this is the best ALL-OUT exhaust setup on the 370z.

If the following parts are installed
- Stillen Gen 3 CAI
- VHR intake manifold (with intake runner smoothed out)
- my custom Throttle body
- Uprev / EcuTek

I predict it will outperform the Z1 setup that had a result of 342whp with one of our 370z member on their dynojet.


My guess is by over 10whp from what I already gained previously from stock to fully modded
256whp to 324whp = 68whp of gain with my previous less optimized exhaust & HR intake manifold
*WITHOUT VVEL TUNING*

when Z1 only got a gain from stock to fully modded including their secret mod to 62whp of gain and Mike the owner of that Z did said they tuned the VVEL ( from 280 to 342 )

Why am I selling ?
Going another route. and no im not selling the Z

Christmas's special price of 3000$

the kit is evaluated at 5000$ with my welding labour and initial installation on my part.

Youtube video of the sweet noise

Inside of the car.
with some 1500-7500rpm pull
cruising speed
and last a 4or 5th gear pull ( cant remember )



Video taken outside of the car by the road and doing a fly-by.



Loud and made for a true hardcore enthusiasm driver and/or racer.


most pictures of the exhaust built can be seen here ( click me )

can you drive over here with your 370z ? I will be glad to install it and go on the dyno...

as I mentioned in the first post . I dont have the VVEL setup anymore which mean doing a dyno with the HR head is irrelevant.

This new custom exhaust has actually a much better flow potential improvement over my previous one.

How did you modify the headers?

Adding a transition and down tube since the throat area was a few tenth thousand under 2 1/4''ID
this help with the scavenging effect of the collector.

Fixed



And thanks for the clarification! I have run through your build of it, but I'm sorry, I did not really look into it that much

[Vnismo370z]

AWESOME! Love the concept! and with V-bands one could change out the HFCs to straight pipes or resonators... GLWS!

[TerribleONE]

Sounds great man. Not a bad deal w the headers IMO

[Megan370z]

Make yourself a favor by buying this setup if are seeking the most N/A power possible.

preferably for a race/track car setup ...

[Megan370z]

Guess what...

Every N/A parts required to gain atleast a minimun of 70+ whp over stock is now for sale. *WITHOUT VVEL TUNING*
Remember I gained 68whp with a less effective exhaust that was made to fit into the decibel limit rules.

This custom 3.5'' exhaust is way more effective than my previous one.

It will be best to be sold as a kit since everything must match together to avoid bottle neck flow problems.

this include every parts that can be seen in this exhaust thread ( CLICK ME )

this package deal add the following parts ;

- Custom CAI which include a bigger Maf Tube
- Custom Throttle body
- NST Light weight pulley kit ( crank & alternator )
- Base Uprev ROM for this setup ( THIS IS NOT A LICENSE).
I just need your ECU part number and the tuned base ROM will be sent to you with the back to stock ROM. *This alone save your $$ on tuning time...*

this package deal price is set at ; 4750$
